In recent years, a variety of image encryption scheme has been proposed. A new color image encryption method based on dynamic key exchange is proposed in this paper. For real time image encryption and lesser amount of time. The algorithm lacks of the characteristic of diffusion because each pixel is operated individually and a chosen/known-plaintext attack can break the scheme. The 192-bit-long...

Secure image communication is becoming increasingly important due to theft and manipulation of its content. Law enforcement agents may find it increasingly difficult to stay afloat above the ill intentions of hackers. We have been able to develop an image scrambling algorithm that is very simple to implement but almost impossible to breach with a probability less than 5x10− 300. This is possibl...

Backgrounds: The prevalence of disordered eating behaviors has been reported to increase in recent decades; therefore, scientific studies should perform for specifying psychological variables that may contribute to the etiology of this disorder. In this study, we examined the role of body image disturbance and perfectionism variables in predicting disordered eating behaviors among female studen...

Digital watermarks have been proposed as a method for discouraging illicit copying and distribution of copyright material. This paper presents a new approach for the secure and robust copyright protection of digital images. The digital watermarks described in this paper are designed to be, as far as possible, invariant against image transformations such as rotation, translation, scaling and cro...

Abstract Nowadays, data are the most valuable content in world. In age of big data, we generating quintillions daily form text, image, video, etc. Among them, images highly used communications. Various types images, e.g., medical military confidential. But, due to vulnerabilities, transmitting such a secured way is great challenge. For this reason, researchers proposed different image cryptogra...
